Wind turbine blades

Darrieus Wind Turbine From Pencils and 3d Printed Parts: Wind Turbines can be divided into two main groups according to the orientation of their rotor shaft: Horizontal Axis Wind Turbines (HAWT) and Vertical Axis Wind Turbines (VAWT). Wind Turbines can also be classified with respect to the principle of o…

Behold the Might Wind Turbine Blade... Just outside of Casey, IA, a wind turbine (windmill) blade stands outside of an I-80 rest stop. It stands some 148 ft. tall, and when my I stood near it, I gotta say, it was an imposing sight. https://www.roadsideamerica.com/tip/39545 #GlobalWindDay #windenergy #localsculpture #CaseyIA #iowa

Description BACKGROUND OF THE INVENTION Many successful forms of wind driven machines have been used throughout the history of man. In recent times, there has been a need to improve the efficiency of these machines, and much work has been done on ever larger and more efficient propeller designs, each utilizing the basic concept of wind as a plane passing over the blades. The basis of the present invention is that wind can be considered as a mass, which although subject to change in form…

Within a two-week time span, there were recently two separate blade failures at Invenergy's Prairie Breeze wind farm. Located in Nebraska, the 200.6 MW project features 1.7 MW GE wind turbines and was newly commissioned. According to Alissa Krinsky, a spokesperson for Invenergy, the blade incidents occurred on April 21 and May 4. No one […]

It's hard to ascertain how many birds fly into the spinning blades of wind turbines and die as a result – and indeed, the topic is so politically charged that I'd recommend a radiation suit before eve…

This is much more efficient.

Camping Wind Turbine: Camping's all about enjoying the outdoors; but let's face it - electronics are hard to power in the outdoors...There's nothing worse than pulling out your camera to snap a photo of a great view and finding out your battery's dead! Generators are hea…

A 100-W helical-blade vertical-axis wind turbine was designed, manufactured, and tested in a wind tunnel. A relatively low tip-speed ratio of 1.1 was targeted for usage in an urban environment at a rated wind speed of 9 m/s and a rotational speed of 170 rpm. The basic dimensions were determined through a momentum-based design method according to the IEC 61400-2 protocol. The power output was estimated by a mathematical model that takes into account the aerodynamic performance of the NACA0018…
